精神发育迟滞(Mental Retardation简称MR)是由各种有害因素影响大脑结构和机能的完善,并引起智能在普通水平以下(IQ<70)和社会适应行为困难的一组疾病,是人类伤残的最大病症之一。不少学者强调MR或有脑部发育异常和病理改变,或有神经生化方面的变化。为此,我们采用RIA法测定MR儿童血清T_4、TSH、FSH、LH、GH的含量,进一步探讨MR儿童神经生化的变化及与病因的关系。本文选择经体检并作智力测验,确诊为
Mental retardation (Mental Retardation referred to as MR) is a set of diseases that affect the structure and function of the brain by a variety of harmful factors and cause intelligence below the normal level (IQ <70) and socially adaptive behavior is human disability One of the biggest symptoms. Many scholars emphasize MR or brain development and pathological changes, or neurobiochemical changes. To this end, we measured the serum levels of T_4, TSH, FSH, LH, and GH in children with RIA using RIA, and further explored the relationship between neuroendocrine changes and etiology in MR children. This article selected by the physical examination and intelligence tests, diagnosed as
